IMO yes but don't put the light too close. Keep it at least 15 inches away and allow the plants to grow into the light. Do you have a cool tube? If not look into one. You might risk burning the crap of of them.

Yeah, go HPS. 18" at first and lower as temps allow.

Obviously you would raise the light, but in the end you want to get the light down to 12" away .. but not at first when they are young and unacclimated to it. So Start out 18" above the tops and let them grow until it's 12" or so and then adjust it as they grow.
